T0 all whom it may concern:

Be it known that I, IRWIN G. BURTON, a' citizen of the United States, and a resident of Asbury Park, in the county of Monmouth and-State of New Jersey, have invented a new and Improved Eyeglass-Protector, of Which the following isa full, clear, and exact description.

The object of the invention is to provide a new and improved eyeglass protector' arranged for convenient attachment to the rims of the eyeglass lenses with a view to protect the lenses against brealng or crackingin case the user accidentally drops the eye lass.

n order to accomplish the desired result use is made of a ring of rubber 0r similar elastic material encircling the riin of the lens and projecting beyond. the faces of the lens.

A practical embodiment of the invention is represented in the accompanying ,.draw ings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a face vieur of a pair of eyeglasses provided with the protector; and F ig. 2 is an enlarged cross sectionl of the protector as applied to a convex lens.

The eyeglass protector consists.. of a ring A, of rubber or other similar elastic material, adapted to encircle the rim of each lens B of a pair of eyeglasses. The ring A, as shown in the drawings is provided with integral inwardly-extending flanges A', A2 overlying the faces of the lens B adjacent the rim thereof, as plainly indicated in Figs. l and The ring A is provided with an aperture A3 for the passage of the post C. of the eyeglass frame of usual construction,

and the ring A also overlies the ears C? held/ on the post C and engaging the riin of the corresponding lens B, as indicated in Fig. 1. In practice, the ring A is less in size than the rim of the lens B and in placing the ring A in position on the rim of the lens B,

lt 1s necessary to stretch the ring A so that the latter lits snugly on the riin of the' lens :B and is thus securely held in place on the lens. By the post C passing through the opening A3 the ring A is held against creeping on the rim of the le is B, and by the ring A-overlying the ears C the latter are' firmly held in Contact with the ri-rn of the lens thus preventing the trarne from becoming loose on the 'lens B.

It :is-understood that the eyeglasses in accidentally dropping are protected by the ring A and its tlanges' A and A2, as the said parts cushion thelenses in' striking on the Y i'ratented June 15, 1915. 1

floor and hence the lenses are not liable to be broken or cracked on accidentally dropping the eyeglasses.

It will also be noticed that the flanges A and i 2 besides forming protecting means for the faces of the lens prevent the ring A troni shifting laterally on the lens. It is understood that the flanges lA and A2 forni projections on the sides of the ring A and extend beyond the edges of the lens B especially it the lens B has its two faces concave. It, however, the lens has a convex outer face, as shown in Fig. 2, the ringis provided vvith an integral extension A4 at the flange A2sc that the outer edge of the eX- tension Al is beyond the point of the curvature of the outer face of the lens B', so that in case the eyeglasses tall flat onto the vfloor the extension A4 protects the lens against y breaking.

If desired, the rim of the lens B may be provided With an, annular recess B2 into which projects a bead A5 formed on the inner face of the ring A to securely hold the latter in position on the lens B.

Having thus described my invention, I claim as new and desire to secure by Letters `latent:

l. A protector for the lenses of eyeglasses, comprising a ring of an `elastic material, less in size than the rim of a lens and having a smooth unobstructed peripheral sur-v tace, the'ring being adapted to encircle the rim and to be held in stretched condition thereon, the said ringprojecting at the sides beyond the edges of the lens and having integral anges extending inwardly on the ring and engaging the faces or the lens adjacent the ri the said ring being provided with aperture located between the flanges for passage of the post of the eyeglass traine, the said ring also overlying the earsheld en the post.

2. The combination with apair of eyeglasses having lenses and a frame, of a protact-ing ring for the rini of each of the said lenses, trie said ring being cian elastic materia-l less in size than the said rim to hold the ring in stretched condition 'on the said riin ci' the lens, the said ring overlyingthe ears or the integral inwardly-extending anges overlens trarne, the said ring having j ing an integral bead-engaging the said re- 3. The combination with an eyeglass'lens having an. annular recess at its rim, of a protecting ring for the rim of said lens, 'the ringbeing of an elastic material adapted i ,name `to this sgyecification in the presence to encircle the riin 'and having inwardly ex*- 'tending flanges overlying 'the faces of the lens adjacent the rim, and an annular bead on said ring engaging the said annular re- QeSS.

4. The combination With a pair of eye- 1of tie lens adjacent the rim, the said lens lia-ving an annular recess at its rim, and the l said ring having an integral bead engagingthe said annular recess.

In testimonyy whereof I have signed my of two subscribing Witnesses.
